Warlock Felguard Pet (might happen with other pets) even though it has 0 mana, it can still use all its spells.Another Felguard bug: it can use intercept from inside minimum range (which is 8yrds) it is a stun, so in pvp this bug could be potentially overpowered and screw ppl up good XD.

Nagrand quest: [The Totem of Kar'dash] is bugged, its an escort quest that when u accept it, the NPC doesnt move like its supposed to.
